Hinode/SOT observations of the June 22, 2010 prominence in the Ca ii H line (top) and in the red wing (0.208 Å from the line centre) of the Hα line (middle) at 15:02 UT. Images are aligned to show the same field of view of 103′′ × 99′′. In the bottom panel we display the Dopplergram showing relative LOS velocities obtained from the Hinode/SOT Hα line-wing observations. Blue represents the movement towards and red the movement away from the observer. The absolute values of the LOS velocities cannot be determined. Axes give the solar X and Y coordinates in arcsec. White ellipses indicate areas 1, 2, and 3.
